## AI overview

The author describes using the GitHub Copilot coding agent to automate repetitive maintenance across many GitHub repositories. The agent handles assigned issues by creating pull requests, documenting a plan, and iterating based on review comments. The author also created GitHub Repo Maintainer to identify repositories needing specific maintenance tasks and create detailed Copilot issues.

## Source excerpt

I have a problem: I'm addicted to making new repositories on GitHub. As part of my advocacy role at Microsoft, my goal is to show developers how to combine technology X with technology Y, and a repository is a great way to prove it. But that means I now have hundreds of repositories that I am trying to keep working, and they require constant upgrades: Upgraded Python packages, npm packages, GitHub Actions Improved Python tooling (like moving from pip to uv, or black to ruff) Hosted API changes (versions, URLs, deprecations) Infrastructure upgrades (Bicep/Terraform changes) All of those changes are necessary to keep the repositories working well, but they're both pretty boring changes to make, and they're very repetitive. In theory, GitHub already offers Dependabot to manage package upgrades, but unfortunately Dependabot hasn't worked for my more complex Python setups, so I often have to manually take over the Dependabot PRs. These are the kinds of changes that I want to delegate, so that I can focus on new features and technologies. Fortunately, GitHub has introduced the GitHub Copilot coding agent, an autonomous agent powered by LLMs and MCP servers that can be assigned issues in your repositories. When you assign an issue to the agent, it will create a PR for the issue, put a plan in that PR, and ask for a review when it's made all the changes necessary. If you have comments, it can continue to iterate, asking for a review each time it thinks it's got it working. I started off with some manual experimentation to see if GitHub Copilot could handle repo maintenance tasks, like tricky package upgrades. It did well enough that I then coded GitHub Repo Maintainer, a tool that searches for all my repos that require a particular maintenance task and creates issues for @Copilot in those repos with detailed task descriptions. Here's what an example issue looks like: A few minutes after filing the issue, Copilot agent sends a pull request to address the issue: To give you a
